Study on the properties of new information discrete GM(1,1) model
2010
This paper studied the parameter properties of new information discrete GM(1,1) model(NDGM) and its fitness to the geometric sequence.This paper puts forward a segmental corrected NDGM model(SNDGM) and studies its modeling mechanism,proves that the initial value of the raw sequence does not affect the development coefficient value and expands the SNDGM model,and solves the fitness precision problems in the case that the raw data is of the segmental geometric sequence.The results indicate the NDGM model can completely fit the geometric sequence and the SNDGM model can completely fit the segmental geometric sequence.
